T o all whom t 'may concern:

Be it known that l; ERIC E. HALL, a citizen of the United States; and a resident of Chicago, in the county of Cool( and State of llllinois, have invented certain new and useful Improvements in Ceiling and Floor Constructions, of whichthe following is a full,-

clear, and exact specification.

My invention is concerned with ceiling and floor construct-ion. and is designed to produce such a construction that 'can 'be quickly and cheaply constructed, and which nevertheless will be accurate and durable.

To illustrate my invention; l have annexed hereto six sheets of drawings in which the same reference charac-ters are used to designate identi 'al parts in all the figures,`of which- Fig. 3l is "a section on the line 3--3 of Fig.` 4 is a side elevation of a novel anchor employed in carrying out my invention with a portion of its top and bottom broken away;

Fig. 5 is a perspective view of a connecting piece;

Fig. 6 is a central vertical longitudinal section of the anchor seen in Fig. 4;

Fig. 7 is a section on an enlarged scale showing the suspended ceiling construction;

Fig. 8 is a section on thc line 88 of Fig. 7';

Fig. 9 is an enlarged section as seen on the line 9-9 of lFig. 7;

Fig. 22 is a longitudinal section on the line 22-22 of Fig. 21; and

Fig. 23 is a detail in cross section on the line 223-23 of Fig. 2l.

My invention is concerned with a-novel suspended ceiling and floorconstruction for `use in buildings employing concrete floors,

and in such buildings the floor may be formed of transverse parallel beams of concrete, spaced apart a suitable distance, and ordinarily provided with reinforcing rods 31 extending through the lengths of the beams. yFormed integrally with these beams 30 are the thinner connectingflooring 32; and in the formation of such beams and flooring, it is customary to build up the false work. 33 which is provided with the channels 34 to form the beams and the surfaces 35 on which the body of the floor rests. After this false work has been built up, the reinforcing rods 31 are laid and the concrete poured in and finished off in the customary manner, and'it will be understood that the construction of thebeams and concrete floors per se form no part of my present invention.

'llo conveniently and cheaply secure thereon the ordinary tongue and groove wooden liooring 36; I secure on the false work 33 preferably at the center of the portions between the troughs 34 and the anchors 37. which, as best seen in Figs. 4. and @,consist of cylindrical tops`.and bottoms having the internally threaded ends 38 connected by the flattened anchor portion 39, which portion it will be understood is provided so that the anchors cannot be withdrawn from the concrete'when it is set. When these anchors are secured in place on the false work 33, they have special wood screws with machine screw threads 40 to take the place of the ordinary head screwed into the threaded, lower ends.

and the wood screw portions 41 in turn are i. 37a. If it is a flat slab flooring the anchors 37 shown in Figs. 4 and 6 may be employed screwed into the false work soithat the anchors can be secured in place in the regular lines or rows shown in Fig. 1. It will be understood that these anchors are of the length corresponding to the thickness of the body of the loor,and when the concrete is being poured, the upper ends are closed by the screws 42 screwed into the threaded tops for this purpose. After the concrete flooring has hardened, and the wooden flooring is to be put in place, the screws 42 are removed and the angular connecting pieces 43, shown 1n Fig. 5, are placed on top of the flooring with one of their apertures 44 therein registering with the tops of the threaded apertures 38 and the screws 42 are again applied tosecure the connecting pieces 43 in place. These connecting pieces are preferably cut from strips of sheet metal of the proper size and thickness-to receive the floor sleep; ers 45 which are placed thereon and are thus supported substantially on the top of the concrete flooring 32. The ends of the connecting. piece 43 are then turned up and the nails 46 are driven through some of the apertures 44 to secure the floor sleepers 45 in place,`as will be readily understood. Once the floor sleepers 45 are secured in place, the tongue and groove flooring 36 can then be nailed thereon in the customarfmanner, and a thoroughly satisfactory flooring is thus produced, and it will also be understood that any deadening material that is desired can be interposed between the tongue and groove flooring 36 and the top of the ooring 32. t will of cour-'se be understood that when the false work 33 is removed, the screws 4() may be removed or clipped olf, if desired. v

For the basis of the support for the suspended ceiling, I employ similar anchors 37 which, if they are `to be inserted at the bottom of the beams 30, are preferably shaped as shown in Fig. 10, the; upper cylindrical portion being omitted` and the anchor portion 39 .being shortened to the form 39, which -is sufficient to 'embed .the anchor in the concrete and also to fbeused for screw- -ing the wood screw portion 41 into place 'in the false work 34 to position the anchors.l

.and it will be understood that these anchors.

37a are alsfoiplaced in rows, as clearly shown in Fig. 1.-" When the-false work has been removed, the. screws 40 are also removed and rods 47 having ltheir upper ends screwthreaded and cut to thedesired length are screwed -into the bottoms of the anchors so that the same anchors are used to hold the floor sleepers and .suspendl the ceiling, as shown in Fig. 17 The lower ends of these rods 47 are bent at right angles, and arel adapted to lit into somegform of av skeletonized metallic bar. one form 48-of which is shown in Figs. 7, 8 and 9, where it will be4 seen to consist of the horizontal side flanges connected by U- or V-shaped troughs. This trough portion is preferably provided with the large recesses 49 in the bottom thereof, which recesses are provided primarily to permit plaster to pass therethrough, and also with the smaller slightly elongated and staggered recesses 50, located at suitable intervals and designed primarily to have the wire nails 51, or some similar fastenineh member, passed therethrough and over the Iiorizontal end of the rod 47, so that the skeletonized bar 48 is suitably supported from the ceiling. Vith this form of bar, I preferably construct the ceiling of layers of plaster-board 52, which plaster-board is well known in' the art, and it will b'e understood that the edges of said plaster-board fitunder the horizontal flanges of the rib, and that it is held in place by the nails 51, which will be passed through the apertures 50 int'connection with each of the rods 47 and at as many other places as may be necessary to suitably support the plaster-board. After the plasterboard has Abeen secured in place, a bottom coating of plaster 53 with any suitable finish on its under surface is applied, thus finishing the ceiling.

In Figs. 11 and 12, I have illustrated a possible substitute forthe anchors 37and 9 the rod 47'in a rod,47a having its upper end 47 bent over and with sheet metal or other angular anchor pieces 47c riveted thereon and adapted to position the rod to suspend the ceiling at its proper height by their cooperation with apertures 47d bored 1n the false work 34. After the concrete has hardended the false work is easily remoued without injuring the rod, the lower end of which can be bent up at right angles at the proper lpoint, but this construction is somewhat inferior to the one employing the anchors 37a and the threaded'rod 47 inasmuch as it is not possible to secure the nicety of adjustment that is possible by screwing the rod 47 into or out of the anchor 37,

In Figs. 13 and 14 I have illustrated a construction like that shown in Figs. 7, 8 and 9 except that the skeletonized metallic bar 48"L has been modified in its design, and the single set of enlarged apertures 50 have been substituted for the apertures 49 and 50 of theform shown in Fig. 7, and the flanges have been turned down. The same rods 47 are employed and the bars 48a secured thereto bythe same nails 51, but I have shown the ceiling here'as formed by an ordinary expanded metal 54 wired at suitable intervals to the bars 48` and having vthe plaster 53 placed thereonvin the customary manner.

In'Figs. 15 and 16, Ishow a modification in which th'e'same hangers 37 and threaded rods 47 are employed, but the reinforcement is `formed by a wire mesh 55, which has the skeletonized bar preferably formed intelll shown in Figs. 18 to 23. lin the form shown remote 'grally therewith lby introducing into the mesh at suitable'inter'vals a pair of larger wires 56,' and forming between said larger wires afchannel 57 in the body of the mesh.

nails '1 in the customary manner, and that the plaster 53 -can be applied thereto the same as to the expanded metal.

l'prefer' employing a 'special form of eX- panded metal, such for instance as the Vform in Figs. 18 to 20, the body 5.8 of the expanded metal is preyidflwith a slreletonized rib by forming therein a troughslike portion hav- V ing the solid bottom 59l and the skeletonized sides 60, and it will be understood that the ends of the hangers can be secured in the troughs bythe nails 5l in the same manner as in the other forms shown and when the expanded metal has been placed, the plaster 53 can be applied thereto yas in the other forms shown. ln Figs. 21 to 23, l have shown anotherl special forni ot expanded metal in which the customary body portion ttl 58 is provided with the skeletonized ribs formed by the depressed channel Yformed byl the skeletonized portion 61 between the adj acentuncutportions 62 being depressed into the generally`U=shjaped form shown in Fig. 23, thus producing a skeletonized channel in which the horizontal ends of the rods 4:7 can be secured inthe same manner as illustrated,

in connection with the other forms of my invention.

l have heretofore pointed out that with theconstruction shown, the heightv ofthe- `ceil1ng can be adjusted to a nicety, andit will be furtherapparent that ,if for any' 'reason it isy desired to produce ceilings of different heights, this can be readily done in any part of the building simply by changing thelength ot the rods 47. l have found by actual experience that this ceiling can be built at a very considerablel saving in co'st over any similar ceiling, and that it is just `as good, it 'not better than the more expensive ones which it replaces.

While ll have shown and described my invention as embodied in some ot' the forms which l at present consider best adapted to carrying out these purposes, it will be understood that it is capableof modifications, and that ll donot desire to be limited in the interpretation of the following claimsexcept as' may be necessitated by the state ot the prior art.

`What l claim as new, and desire to secure ,by Letters Patent of the United' States is:
